Mind games? Can you elaborate? Example? Is it a mild sadistic streak?

Do you consider these people your friends? It sounds like you do to some extent since you think yourself as a fake friend. Meaning you initially thought yourself as their friend?

I also agree with Sisabel, and to add to her post. Does not liking someone mean you treat them with disrespect? As she said, it sounds like you're simply being proffesional.

Lastly, unless there's a limit to how long you cab speak to a therapist and that you have other talking points that will last a whole session, I don't see any harm in bringing up both of these issues. If only to gain another opinion on the topic.
